Feng Zheng continued to train for another week.
During this time, after Hiruzen finished his training, Feng Zheng would return home, close his eyes, and create a Vacuum Core with his palms.
He did this to become more familiar with the process of creating a Vacuum Core.
Eventually, Feng Zheng successfully created a stable Vacuum Core in his mouth.
He performed a few Hand Seals and blew out a Vacuum Bullet Technique.
Unlike the Vacuum Bullet Technique, which can only create one Vacuum Bullet at a time, the Air Bullet Technique can fire six Air Bullets simultaneously.
It traveled in a straight line for forty meters, piercing through everything in its path!
Feng Zheng laughed.
“That’s awesome!”
Hiruzen also smiled.
This time, Feng Zheng’s performance was exactly as he had expected.
Of course, his expectations were even higher.
Hiruzen said, “Well done, Feng Zheng.
You can further improve the Vacuum Bullet Technique by creating more Vacuum Cores so you can use multiple at once.
Of course, this isn’t easy, so don’t rush it.”
Feng Zheng nodded.
He would need to use this Ninjutsu many times in the future, and his mastery of it would steadily improve.
Hiruzen continued, “Besides the Vacuum Ball and Vacuum Bullet Technique, more Vacuum Ninjutsu can be created by changing the shape of the Vacuum Core.
But don’t try it for now; try it a few months later.”
Feng Zheng nodded and said, “Thank you, Grandpa.”
Hiruzen smiled, seeing how obedient he was.
However, he soon noticed a slight smile on Feng Zheng’s face.
Feng Zheng continued to ask, “Grandpa, it’s only nine in the morning, and there’s still some time until training ends.
Can you teach me how to focus Chakra into my eyes?”
Hiruzen’s eye twitched!
He exclaimed in his heart, “Next time there are negotiations, I’ll send this shameless brat to negotiate!”
Feng Zheng analyzed, “Although I’m confident in my Chakra control, the eyes are a sensitive organ.
I don’t want to hurt them.
It would be best if Hiruzen could guide me.”
Hiruzen just sighed and agreed.
He also had nothing to do, as Homura Mitokado was still working for him.
Hiruzen instructed Feng Zheng on how to focus Chakra into his eyes, which required meticulous Chakra control, but it was effortless for Feng Zheng.
Hiruzen gave him some tips and then sent him away.
He was indeed worried that Feng Zheng would ask him to teach him more.
Feng Zheng also knew that he had made many requests to Hiruzen in the past few weeks.
So he thanked him and left.
After leaving, Feng Zheng thought, “What should I do now?
Should I rent a Training Grounds and continue training?
Since Hiruzen took over our training, I haven’t heard from Renjiro.”
He thought for a moment and then walked towards the Senju Clan compound.
He decided in his heart, “It’s time to redeem that Rank A Ninjutsu from Renjiro.
Do I need to specifically request something?
I really can’t remember any useful Rank A Ninjutsu.
Wind Blade is the only thing that comes to mind, but I don’t urgently need it right now.
I’ll just ask him to give me some suitable Ninjutsu.”
Feng Zheng went to the Senju Clan compound.
However, Renjiro was out on a mission.
So Feng Zheng rented a Training Grounds and practiced the Vacuum Ball and Vacuum Bullet Technique.
After sending Feng Zheng away, Hiruzen returned to his office.
Seeing Hiruzen enter, Homura Mitokado was furious!
He said in an ill-tempered manner, “Hiruzen, you finally remembered to come back?”
Hiruzen shrugged and said, “Today’s training is over.”
Homura Mitokado said coldly, “You taught one Ninjutsu for sixteen days?
At least say something convincing!”
Hiruzen did not answer.
Homura Mitokado realized that Hiruzen was serious.
He asked, “What exactly did you teach?”
Hiruzen replied, “Well, one of the children asked me to teach him Wind Vacuum Technique.”
Homura Mitokado’s eyes widened.
He asked, “Did you really teach him?”
Hiruzen nodded.
Homura Mitokado cursed, “Hiruzen! This Ninjutsu is too dangerous for a ten or eleven-year-old child!”
Hiruzen waved his hand, dismissing Homura Mitokado’s concerns.
He said, “Don’t worry, that kid is very promising and mature enough not to use it on his comrades.”
Homura Mitokado asked, “Which child?”
Hiruzen replied, “Suzuki Kazemasa.”
Homura Mitokado frowned.
He asked, “That orphan?
I thought you set this reward to appease the Uchiha Clan.”
Hiruzen nodded and said, “I also taught her a Rank A Ninjutsu, which is already a good reward.
However, I found that Feng Zheng is also very talented and has the potential to become an Elite Jonin.
Since he specializes in Wind Release Ninjutsu, he would be an excellent addition to most of our Jonin teams.”
Homura Mitokado was surprised by Hiruzen’s high praise.
He nodded and said, “If the Village can have another Elite Jonin, then there’s no problem.
Are you planning to bring him into the Anbu?”
Hiruzen nodded.
“Yes, but recruit him when he turns thirteen.
We’ve already broken tradition for Itachi because of the Uchiha Clan’s situation.
There’s no need for Feng Zheng to break this tradition again.
Additionally, we still need to observe his performance as a Chunin.”
Homura Mitokado nodded.
Chunin is a critical stage that distinguishes ordinary Ninja from elite Ninja.
Many Ninja, after becoming Chunin, get tired of training and stop or slow down their training pace.
After all, not every Ninja can motivate themselves to train for life.
Such Ninja rarely manage to advance their rank.
Konoha would not waste any more effort on them.
Three days later, Renjiro appeared on the Training Grounds where Feng Zheng was training.
Feng Zheng, who had just started training, sensed his arrival and stopped.
Renjiro flickered beside Feng Zheng.
He was about to speak but then noticed a pile of holes in every tree and boulder around Feng Zheng.
He was speechless for a moment.
He looked at Feng Zheng and asked, “What did the Hokage teach you?”
Feng Zheng smiled and said, “He taught me Wind Vacuum Technique.”
Feng Zheng extended his arm and fired a Vacuum Ball.
Renjiro watched in astonishment as it pierced through more than a dozen trees!
He was stunned!
He was very puzzled, “Did he really convince that old man to teach him Wind Vacuum Technique and learn it in less than three weeks?
I know he’s talented in Wind Release, but to this extent?”
After the disbelief passed, he was also proud of his student.
However, after hearing his student’s words, Renjiro’s face immediately darkened.
Feng Zheng asked, “Teacher, where have you been?
I wanted to ask you to teach me a Rank A Ninjutsu!”
Renjiro stared at Feng Zheng, who looked back innocently with a smile on his face.
He sighed and asked, “Have you decided what Ninjutsu you want?”
Feng Zheng shook his head and said, “Teacher, I trust your judgment.
You will provide a Ninjutsu that suits me.”
Renjiro nodded.
Rank A Ninjutsu are hard to find.
Suitable Rank A Ninjutsu are even rarer.
Feng Zheng did know some Rank A Ninjutsu, but most were of other elements.
The remaining ones were very few, so he couldn’t determine which would be most useful to him.
Renjiro said, “Alright, I’ll teach you the Shadow Clone Great Explosion Technique.”
Feng Zheng thanked him, “Thank you, Teacher.
Can we start learning now?”
Renjiro had just returned from an Rank S mission.
He originally planned to rest, but he still agreed.
Renjiro said, “This Ninjutsu has no Hand Seals.
You just need to create a Shadow Clone and use all of its Chakra to make it self-destruct.”
Feng Zheng replied, “Teacher, that’s very convenient.”
Renjiro nodded and continued, “The advantages are obvious, and the limitation is the range.
Your Shadow Clone needs to be very close to the enemy to self-destruct, while also ensuring the enemy doesn’t quickly leave.
As for the disadvantage, because your Shadow Clone will use up all its Chakra, you won’t get any Chakra back.”
Feng Zheng nodded.
It was just as he had expected.
Feng Zheng asked, “So how do we make the Shadow Clone explode, Teacher?”
Renjiro began to explain the Ninjutsu details in depth.
Feng Zheng created several Shadow Clones and had them try it according to the points Renjiro explained.
Feng Zheng observed them carefully.
A few minutes later, one of the Shadow Clones successfully exploded!
The explosion raised dust.
After the dust settled, he noticed a small crater where the Shadow Clone exploded, with a radius of about 2 meters and a maximum depth of 5 centimeters.
Soon, the second Shadow Clone also exploded.
Feng Zheng received the memories and experiences of the two Shadow Clones.
He began to create more Shadow Clones one after another.
When one self-destructed, Feng Zheng would gain its experience, and then create another Shadow Clone to practice the Ninjutsu.
Since learning the Shadow Clone Technique, Feng Zheng’s Chakra had increased significantly, many times over.
He could now create twenty-one normal Shadow Clones that could sustain themselves until two-thirds of their Chakra was depleted.
If he only created Shadow Clones for the sake of creating them, he could create 65 Shadow Clones!
Of course, these Shadow Clones couldn’t use too much Chakra.
If he wanted his Shadow Clones to use Rank B Ninjutsu or stronger Ninjutsu, he could only create a few.
However, because it was just for learning how to self-destruct, Feng Zheng created thirty of them one after another.
This exhausted eighty percent of his Chakra reserves!
However, his progress was astonishing!
